The year 2025 marks a pivotal turning point for stablecoins — with major regulatory milestones, groundbreaking financial innovation, and the long-anticipated public listing of Circle, the issuer of USDC. From Hong Kong’s pioneering Stablecoin Ordinance to the final stages of the U.S. GENIUS Stablecoin Act, the global financial architecture is being redefined. Stablecoins are no longer fringe digital experiments; they have officially entered the mainstream financial arena.
What Are Stablecoins?
Stablecoins are a unique class of cryptocurrency designed to maintain a stable value by being pegged to external assets such as fiat currencies, commodities, or through algorithmic mechanisms. They address one of the core challenges of traditional cryptocurrencies: extreme price volatility. By offering price stability, stablecoins serve as reliable mediums of exchange, stores of value, and units of account in both decentralized and traditional financial ecosystems.
Fiat-Collateralized Stablecoins
These are backed 1:1 by reserves of fiat currency — typically the U.S. dollar — held in regulated financial institutions. Every issued token corresponds to an equivalent amount of real-world currency in reserve. Prominent examples include Tether (USDT) and USD Coin (USDC).
Interestingly, Hong Kong’s Linked Exchange Rate System — where the Hong Kong dollar is pegged to the U.S. dollar — can be viewed as a real-world analog of a fiat-collateralized stablecoin. This parallel highlights how digital stablecoins extend the reach of dollar dominance into the virtual economy, reinforcing what some call the "dollar standard 3.0" — evolving from gold-backed, to debt-backed, and now to blockchain-secured.

Crypto-Collateralized Stablecoins
Backed by other cryptocurrencies like Ethereum or Bitcoin, these stablecoins require over-collateralization due to the inherent volatility of their underlying assets. For example, to mint $100 worth of **DAI**, a user might need to lock up $200 worth of ETH. This buffer protects against sudden price drops. DAI, issued by MakerDAO, remains the most prominent decentralized stablecoin in DeFi.
Commodity-Collateralized Stablecoins
These derive value from physical assets such as gold or silver. Each token represents ownership of a specific quantity of the commodity stored in secure vaults. Paxos Gold (PAXG), for instance, is backed by one gram of LBMA-approved gold per token, combining blockchain efficiency with tangible asset value.
Algorithmic Stablecoins
Unlike asset-backed models, algorithmic stablecoins use smart contracts and supply adjustments to maintain price stability. When prices fall below par, the system reduces supply; when prices rise, it mints more tokens. While innovative, this model has faced challenges — most notably with the collapse of TerraUSD (UST) — underscoring the importance of robust design and market confidence.
Key Use Cases Driving Adoption
Stablecoins are not just speculative tools — they fulfill critical roles across modern finance.
Medium of Exchange in Crypto Trading
In volatile markets, traders use stablecoins as a safe harbor during uncertainty. Instead of converting holdings back to fiat — a slow and costly process — users switch to USDC or USDT instantly. This makes stablecoins the de facto trading pair on most exchanges, enhancing liquidity and reducing slippage.
Cross-Border Payments & Remittances
Traditional cross-border systems like SWIFT are slow, expensive, and increasingly weaponized in geopolitical conflicts — as seen with sanctions on Russia. Stablecoins offer an alternative: near-instant settlements at a fraction of the cost.
According to CEX.IO, stablecoin transfer volume reached $27.6 trillion in 2024, surpassing combined transaction volumes of Visa and Mastercard. In emerging economies, stablecoins are already used for salary payments and everyday transactions, bypassing unstable local currencies.
Hong Kong’s new Stablecoin Ordinance, effective May 30, positions the city as a leader in regulated digital finance. It mandates licensing for any entity issuing fiat-backed stablecoins — including those pegged to the Hong Kong dollar, regardless of jurisdiction. This "value-anchored regulation" model is distinct from the EU’s MiCA framework and Singapore’s tiered licensing, giving Hong Kong a strategic edge in attracting Web3 innovation and advancing offshore RMB digitalization.

Store of Value in High-Inflation Economies
In countries experiencing hyperinflation — such as Argentina, Nigeria, or Turkey — citizens increasingly turn to dollar-pegged stablecoins to preserve wealth. With mobile internet access, anyone can safeguard savings from currency devaluation without relying on traditional banking systems.
Leading Stablecoins by Market Presence
Tether (USDT) – $150.3B Market Cap
Launched in 2014, USDT remains the most widely used stablecoin, operating across multiple blockchains including Tron and Ethereum. Despite past transparency concerns, its deep integration into trading platforms ensures continued dominance.
USD Coin (USDC) – $60.8B Market Cap
Co-launched by Circle and Coinbase in 2018, USDC stands out for its regulatory compliance and monthly attestations by independent auditors. Its transparency has made it a preferred choice for institutional players and compliant DeFi protocols.
Coinbase reported $910 million in stablecoin revenue in 2024, up 31% year-over-year — driven by interest from USDC reserves, trading fees, issuance/redemption charges, and ecosystem growth.
Ethena USDe – Up to $3.6B Peak Market Cap
Launched in 2024, USDe uses delta hedging with staked ETH, BTC, and SOL to maintain its peg — effectively creating a synthetic dollar yield without direct Treasury exposure. It represents a new wave of decentralized finance innovation.
DAI (MakerDAO)
As a crypto-collateralized stablecoin governed by a decentralized autonomous organization (DAO), DAI plays a foundational role in DeFi lending and borrowing markets.
Circle’s IPO: A Watershed Moment
On May 27, 2025, Circle filed with the U.S. SEC to go public on the NYSE under ticker CRCL. The company plans to raise up to **$624 million** by offering 24 million shares priced between $24–$26. Backed by BlackRock and ARK Invest’s Cathie Wood, Circle’s listing completes a crucial piece of the crypto investment puzzle.
With **$1.68 billion in 2024 revenue** and profitability confirmed ($156 million net income), Circle joins Coinbase and bitcoin ETFs as a cornerstone of regulated crypto finance. Its acquisition of Hashnote — issuer of USYC and backed by Cumberland Labs, a leader in tokenized Treasuries — further strengthens its position in real-world asset (RWA) finance.
Other players like BitGo, Gemini, and Bullish are expected to follow suit, signaling a wave of institutional legitimization across the sector.

Frequently Asked Questions (FAQ)
Q: Why is Hong Kong’s Stablecoin Ordinance significant?
A: It establishes a clear regulatory framework for stablecoin issuers, especially those referencing the HKD. Its extraterritorial reach sets a precedent for global oversight and boosts Hong Kong’s status as a Web3 hub.
Q: How do stablecoins challenge traditional banking?
A: By enabling faster, cheaper cross-border transfers and financial inclusion without intermediaries, stablecoins reduce reliance on legacy systems like SWIFT and central banks.
Q: Is USDC safe compared to USDT?
A: USDC is considered more transparent due to regular audits and strict compliance standards, while USDT has faced scrutiny over reserve composition — though both remain highly liquid and widely accepted.
Q: Can stablecoins replace fiat currencies?
A: Not fully yet — but they’re becoming parallel systems, especially in regions with weak monetary policy or capital controls. Over time, CBDCs and private stablecoins may coexist.
Q: What role does Circle play in the broader crypto ecosystem?
A: Beyond issuing USDC, Circle drives innovation in regulated fintech, RWA tokenization, and global payment rails — positioning itself as a bridge between traditional finance and Web3.
Q: Are algorithmic stablecoins viable long-term?
A: Only if they incorporate sufficient risk controls and collateral buffers. Pure algorithmic models have proven fragile; hybrid approaches show more promise.
